What is the primary way to control a mold problem?

• A. Controlling moisture
• B. Killing mold spores
• C. Applying pesticides
• D. Increasing humidity

Answer: (A)

Mold growth hinges on moisture. If you remove the moisture source and keep the environment dry, mold can’t thrive and existing growth will stop or die back. Spores are everywhere, so simply trying to kill mold isn’t enough long-term—the problem will return as soon as moisture is present again. Pesticides don’t address the underlying cause and can be ineffective or unnecessary, while increasing humidity actually fuels mold growth. To control mold, focus on moisture management: fix leaks and water intrusion, repair plumbing and roof issues, improve drainage away from the building, dry out damp areas promptly (ideally within 24–48 hours after water exposure), use dehumidifiers or air conditioning to maintain relative humidity below about 50–60%, and ensure good ventilation in damp spaces like bathrooms and kitchens. In larger or hidden cases, professional remediation may be needed to safely remove growth and prevent recurrences.
